ten2pwr6 Posted July 1, 2020 Share Posted July 1, 2020 HP Probook 470 G5 ... I am fine with BIOS v1.08.01 ... anything above that freezes on boot. Attached are text file export of the 1.08.01 and 1.10.01 DSDT from CLOVER. I tried DiffMerge to see the difference... but it's all greek (geek) to me. Any help would be appreciated.

Moderators Jake Lo Posted July 1, 2020 Moderators Share Posted July 1, 2020 Freezes when booting MacOS or Windows too? If just MacOS, then please attach your Clover files. Link to comment Share on other sites More sharing options...
ten2pwr6 Posted July 1, 2020 Author Share Posted July 1, 2020 ..this is the same issue as the OP described here... which is why I didn't add the Clover files... this is a "what is different with these BIOS files" that's breaking the boot. OS X won't boot when BIOS updates from 1.08.01 to anything higher. Windows is fine... only OS X with the BIOS Update attempt.. I have to keep down-grading back to 1.08.01 I"m comparing these files and I see that I can add... change H_EC to EC which wasn't there before.
